Function type_id

pub const fn type_id<T>() -> u128
where T: 'static + ?Sized,
🔬This is a nightly-only experimental API. (core_intrinsics)
Expand description

Gets an identifier which is globally unique to the specified type. This function will return the same value for a type regardless of whichever crate it is invoked in.

Note that, unlike most intrinsics, this is safe to call; it does not require an unsafe block. Therefore, implementations must not require the user to uphold any safety invariants.

The stabilized version of this intrinsic is core::any::TypeId::of.
